[QUOTE="deepbluesky, post: 69446, member: 176074"] The people here [url]http://www.msg-shop.gr/[/url] told me that to get the BBCs in Crete is quite a hard job. They did some installations there. Sometimes a 5m was enough, other installs quite close were struggling on 6m as far as i remember. In Athens which is far more north you need 5m.
